My endo says the same thing 30-40 minutes window. If conscience give the stress dose in pill form.

We have had several broken bones, one serious enough to operate on. I gave stress dose in pill form and he was fine.

 

When there is a hot sweety  game I give a stress dose. and lots of water, and salty foods. This seems to get them through. Before when I didn’t do this they got run down, and dizzy, thought they were going to pass out, and had severe headaches.

Hope this helps
